AD9361 Output power,Gain

I have measured the Output power from AD9361 for different Input powers arying from -110 dBm to -50dBm and plotted the graph of Input vs Output power attached in the figure.I used the Manual gain control mode. the Output power was linearly varying with the gain as shown in the figure untill -90dBM but from then (for Input powers of -100dBm and -110dB,)the Output power almost became constant.Can you let me know the reason for this.


Does the AD9361 react only for certain Input powers. I repeated my calculations several time but always below -90dBm the Output power is not linear witht respect to the Input power.


Please can you explain me the reason for such a behaviour.
